Thanks for the feedback can you elaborate how much time needed for calender spread and cash to future arbitrage orders .

But still my query remain unanswered , when IIFL, finvasia , composite edge, indira secuirities master trust can offer algo trading with symphony , greek soft , omnesy why zerodha does not extend platform to its customers for algo arbitrage ?
In the end zerodha will get business if these broker can get approval within three months why zerodha can not ?
